Lastly, there's the NH Vital Records website, which proudly notes that "Genealogical & Vital Records are not available online." They do have an online tool for statistical analysis of vital records, so I suppose that's something.

I couldn't even get a historical photo of New Hampshire from the state archives website, and had to swipe one from Flickr Commons. What a shame that a state with such a rich history has so little to offer in this internet age.

Update: All is not lost, it seems. Thanks to an alert visitor for pointing out NHDeeds, with links to the Register of Deeds databases in counties throughout New Hampshire. Each county has a different track record in terms of what's available, but you can generally search by family name for records of interest. Also have a looks at NH State Records, large downloadable files of state papers, including probates, back to the 1700s. Check the Index file for lists of names included in the records.
